. 4 Claims. 1

My present invention relates to an improved truck tire mounting anddemounting attachment for hydraulic lifts and particularly adapted foruse in removing rusted and frozen tires of large size such as are usedin heavy trucks, as well as mounting new or repaired tires wherein thephysical strength normally required is eliminated.

In the accompanying drawings I have illustrated one complete example ofthe physical embodiment of my invention according to the best mode Ihave thus far devised, but it will be understood that various changesand alterations may be made in the exemplified structure with in thescope of the appended claims.

In the drawings:

Fig. 1 is a perspective view of the apparatus of my invention shown inposition for use on a conventional hydraulic lift.

Fig. 2 is a vertical sectional view of the apparatus ready to mountatire on its rim.

Fig. 3 is a similar view with the lift raised and the tire mounted.

Fig. 4 is a plan view of the eye bolt imbedded in concrete below thelift.

Fig. 5 is a vertical sectional view of the demounting arrangement.

Fig. 6 is a similar view with the tire removed.

Fig. 7 is a vertical sectional View of the modified apparatus to operatewith demountable rims.

Fig. 8 is a top plan view thereof.

Fig. 9 is a top plan view of a pressure ring.

In carrying out my invention I utilize the COD" ventional hydraulic liftused in garages and filling stations for elevating vehicles for serviceand having spaced beams 2 and i. I prefer to use a pair of angle ironflanges 5 on the inner edges of the beams to support the ring 8 havingan upper head iii. In mounting a tire the'rim i2 is placed on the ring 8with the usual flange l3 against the bead iii and the tire M ispositioned on the rim 6 2 with the locking ring it in place.

A second ring is having a lower bead 2t resting on the tire wall nearthe tire bead has a pair of angle irons 22 across the open center of thering to receive a cap it formed with beveled To dismount a tire from aWheel the tire I4 is placed on the ring E8 in inverted position and adepressed cap 26a in the axle opening of the wheel secures the bolt 28as stated above. When the lift is raised the wheel is held stationarywhile the tire is forced up and off of the wheel as in Figs. 5 and 6';

For demountabl rims as seen in Figs. 7 and 8 I provide a spider frame 36having arms 38 notched at 39 and pivotally secured to the frame by pins59. These arms engage the edge of the rim l2a while the ring l8 engagesthe tire to force it off when the lift is raised.

Qbviously rings of various sizes will be available to accommodate tiresand wheels of different sizes and it will be apparent that the ring I8is larger than the ring, 8 so that the larger ring will encircle thewheel or rim engaging the tire wall.

Having thus fully described my invention what is claimed is:

1. A demountable tire attachment for a hydraulic lift having afoundation with spaced parallel beams positioned above the foundationand adapted to be elevated therefrom by hydraulic means, a ring having arolled bead around the upper edge positioned on said beams, a socketsecured in the foundation and positioned midway between the beams, avertically disposed rod having a head on the upper end, a hook on thelower end engaged in the socket in the foundation, and means anchoringthe head of the rod to the rim of a Wheel positioned on said ring.

2. A demountable tire attachment for a hydraulic lift having afoundation with spaced parallel beams positioned above the foundationand adapted to be elevated therefrom by hydraulic means, a ring having arolled bead around the upper edge positioned on said beams,a socketsecured in the foundation and positioned midway between the beams, avertically disposed rod having a head on the upper end and a hook on thelower end engaged in the socket in the foundation, and a cap mounted onthe head of the rod for anchoring the rod to a wheel positioned on thesaid ring.

3. A demountable tire attachment for a hydraulic lift having afoundation with spaced parallel beams positioned above the foundationand adapted to be elevatedtherefrom by hydraulic means, a ring having arolled bead around the upper edge positioned on said beams, a socketsecured in the foundation and positioned midway between the beams, avertically disposed rod having a head on the upper end and a hook on 3the lower end engaged in the socket in the foundation, and anchoringmeans having pivotally mounted arms mounted on the rod under the headthereof with the outer ends of the arms adapted to engage the rim of awheel positioned on the said ring.

4. A dernountable tire attachment for a hydraulic lift having afoundation with spaced parallel beams positioned above the foundationand adapted to be elevated therefrom by hydraulic means, a ring having arolled bead around the upper edge positioned on said beams, a socketsecured in the foundation and positioned midway between the beams, avertically disposed rod having a head on the upper end, a hook on thelower end engaged in the socket in the foundation, and meanstransmitting pressure resulting from 4 upward movement of the saidparallel beams to a tire on a rim with the parts anchored by the saidvertically disposed rod and with the resultant force applied to theunder surface of the head of said rod.
